RDA is a new cataloging format that is going to replace the AACR2 cataloging rules. RDA stands for resource access and description andtheoretically it will affect all libraries at some point. For teacher librarians who use various automation systems, those vendors will at some point convert all present records in your catalog to RDA format. While Intner and associates in the Cataloging Correctly for Kids have a brief chapter about RDA, the current primer goes into much more detail. A number of useful guides will probably follow the implementation by the Library of Congress some time in 2011 or shortly thereafter.
